1450 6-roll reversible cold rolling unit is the cold rolling production line with designed annual output of 225 thousand tons and adopts UCM-type single-stand mill.
Four-roll, Six-roll cold rolling mill
It includes models with width range between 650mm and 1450mm, with the highest speed of 1200m/min, the maximum rolling force of 2000T and the maximum coiling tension of 24 tons. It can be used for rolling alloy steel such as 65Mn and 30 CrMo, allows various profile adjustment ways such as positive/negative bending of working roll, bending and twitching of intermediate roll, depressing for deviation adjustment and cooling roll step by step, and can be provided with double-station roll changing carriage, oil-gas lubrication system for roll bearing and automatic rolling line adjustment device. The electric drive system adopts Siemens S7-400 PLC as the main controller and AGC system is controlled by Siemens S7-416+FM458. Key elements, such as EMG automatic centering system, MOOG servo valve, SONY magnetic scale, POLYTEC laser velocimeter and Dr-Brandt tensionmenter, are imported products.
1450mm 6hi cold rolling mill
1. Its usage
To roll high quality cold rolled steel coil( plain carbon steel)
2. Brief Introduction:
The production of this unit is to roll hot rolled coils with the thickness of 2.0～4.5mm into high precision cold rolled coils with the thickness of 0.18～1.5mm through several time of rolling. The scale of the cold rolling production line is a production of 225 thousand tons of cold rolled steel coils per year. It adopts the UCM-type single-stand 6-roll reversible cold rolling mill. The work roll of the rolling mill is equipped with positive and negative bending. The intermediate roll is equipped with positive bending and twitch. The uncoiler is equipped. Both front and rear frames are equipped with coiler, thickness gauge, laser velocimeter etc., which can realize large tension rolling and guarantee high-speed and stable production with specified thinness.
